A Distributed System of Signal Acquisition for Induction Motors Diagnostic

In this paper, the realization of a diagnostic system is presented. The so called "distributed system for induction motors diagnostics" has been developed at our University. The pilot version of this system is installed in one of the Polish power plants. This system consists of three layers: devices, network and management. As device and network layers we propose a tele-measuring system (TMS). This TMS supporting management layer which include diagnostic services (DS) is located in a specialized diagnostic center (SDC). As for data transmission via TMS, the Internet and the Ethernet networks are used as inexpensive reliable links, as it is more cost efficient to provide a remote the maintenance of the DS. The detailed TMS design is described in this article.
